With the spread of the epidemic in China and around the world in 2020, air disinfection and purification has become a hot topic of social public opinion. And the car as People's Daily contact with frequent space, interior air purification has become the focus of attention. In view of the trend that consumers pay more and more attention to the health status of themselves and their families (especially the elderly, children and pregnant women). At present, there is still no system level product that can solve the air quality problem in the car systematically. A survey shows that more than 95% of domestic air purification products in the field of activated carbon adsorption technology, the current market in the field of products, using the technical principle of mostly filter type (physical filter filter, or electrostatic collection filter); There are also parts of the use of adding photocatalyst, ultraviolet lamp, negative ions, etc., these technologies in the air disinfection effect is very limited. Ultraviolet air purification system is a good solution to the problem of air sterilization and disinfection, it uses photochemistry, light plasma and light ionization principle, to purify and disinfect toxic substances in the car, the purification rate of more than 95%. It has the advantages of thorough purification, no secondary pollution, energy saving, low cost, sterilization and so on, so it has been paid more and more attention by people We can design uv air purification products according to the specific needs of different models of air conditioning and customers. And make the product modular, easy installation, disassembly and maintenance. At the same time, we also consider the influence of wind resistance, air treatment time and ozone concentration on people and equipment in the car and other factors, the product has been targeted to optimize the design, try to make it perfect and reliable.
